1. Understanding Aryl and Alkyl Halides: - Aryl halides are compounds where a halogen atom is bonded to an aromatic ring (like benzene), while alkyl halides have halogen atoms attached to aliphatic carbon chains. 2. Bonding Characteristics: - In aryl halides, the carbon-halogen bond is inf...
However, the reaction completely shut down by using Et3N, a frequently used base in palladium-catalyzed Sonogashira coupling of aryl halides (entry 10)11. Lowering the amount of catalyst or reaction temperature led to a reduced yield to different extent (entries 11–12). Control experiments ...

Pd–PEPPSI–IPent has proven to be an excellent catalyst for the Negishi cross-coupling reaction of secondary alkylzinc reagents with a wide variety of aryl/heteroaryl halides. Importantly, β-hydride elimination/migratory insertion of the organometallic leading to the production of isomeric coupling pr...
